Can't be any simpler than that
Then you can discuss the definition of workstation, which in my opinion is something that you can use to:
b. Make sounds with
c. Sample and edit/modify those samples
Any workstation that I've ever seen adheres to those criteria.
So, only with the addition of sampling and recording did Reason become a DAW, IMO.
